6. Combining MORSE and RipEX networks
When expanding a MORSE network with RipEX radio modems, different arrangements are possible.
In the following paragraphs we assume that the whole network is divided into two parts – the MORSE
part and the RipEX part. The two parts are interconnected through two radio modems – one MRxxx
and one RipEX, hereafter referred to as border radio modems. As RipEX and MRxxx radio channel
protocols are not compatible, we strongly recommend you use different frequencies for either part of
the network.
6.1. RipEX part in Bridge mode
There are two basic scenarios:
• Terminal devices are connected to Ethernet interface
• Terminal devices are connected to COM port
6.1.1. Terminal devices connected over Ethernet
If terminal devices are connected over Ethernet, the border RipEX and MRxxx should also be intercon-
nected by an Ethernet cable. The IP addresses of all devices in the network should belong to a single
LAN.
The picture shows MORSE network settings; note the use of Proxy ARP in IP-M-IP mode.

6.1.2. Terminal devices connected to COM
The COM port of the border RipEX and the RS232 of the border MRxxx are connected with a crosslink
serial cable, see Fig. 6.2, “Crosslink serial cable”.
The COM port protocol at the border MRxxx must be the same as protocol used by the other MORSE
devices in the network. In some special cases, the ASYNC LINK protocol can be used for the border
interconnection.
